摘要：Web services are emerging technologies of choice for implementing distributed service models for performing power system operations such as state estimation of power systems in a complete secure, distributed and platform independent environment. The power system applications themselves have been developed in different platforms and language paradigms. Interoperability between power system applications becomes a major issue because of the heterogeneous nature. The main aim of this paper is to propose a model that enhances the interoperability between power system applications by representing the power system data in a more flexible and language independent format (i.e.) in XML and to implement the power system operations in a highly distributed environment. The power system state estimation problem is considered for representation and analysis in a distributed environment. The proposed Web service model using JAX-RPC (Java API for XML-based RPC) for state estimation is highly distributed and has inherent features such as platform independency, interoperability, functionreusability, discoverability and security. A generalized XML based data generation model has been proposed for exchanging data in order to enhance the interoperability between legacy power system applications. The performance of the proposed JAX-RPC model for power system state estimation is compared with the traditional client-server and RMI models using Round Trip Time (RTT) as a measure. (The overhead associated with the proposed model).
